MATLAB: How to make a loop the changes for the specified values

for loop

I am trying to set time increment n such that it always corresponds to a 2 degree increment in TH2 based on current omega2. However, I do not believe my loop is set up to evaluate at a 2 degree increment. I do not know what steps to take to make my code run properly.
w2=2*pi;
TH2=0;
t=2
a2=0.5*t;
L2=50;
L3=150;
for n=1:2:length(w2)
TH3(n)=acosd((L2*cosd(TH2))/L3)
d(n)=((L2*sind(TH2(n)))-(L3*sind(TH3(n))))
w3(n)=(L2*w2*sind(TH2(n)))/L3*sind(TH3(n))
d2(n)=(L2*w2*cosd(TH2(n)))-L3*w3*cosd(TH3(n))
a3(n)=((-L3*w3^2*cosd(TH3(n)))+(L2*a2*sind(TH2(n))))+(L2*w2^2*cosd(TH2(n)))/L3*sind(TH3(n))
d3(n)=(L2*a2*cosd(TH2(n)))-(L2*w2^2*sind(TH2(n)))-(L3*a3*cosd(TH3(n)))+(L3*w3^2*sind(TH3(n)))
end

Best Answer

The problem is that your ‘w2’ is a scalar of size (1 x 1), so the loop is already satisfied at the first iteration.
This might be closer to what you want to do:
for n=1:2:w2
although ‘n’ will increment in radians, not degrees. To have it increment in degrees, change your loop index to:
for n=1:2:w2*180/pi
or just:
for n=1:2:360
EDIT — Also, ‘TH2’ and ‘TH3’ never change, so all calculations derived from them never change.
